System Description: Description
WARNING: This page is about a different car, the 2023 Mitsubishi Outlander PHEV. However, it is still accessible from the selected car via links, so may be relevant.
Outline
- IPDM E/R incorporates a power consumption control function that reduces the power consumption according to the vehicle status.
- IPDM E/R changes its status (control mode) with the sleep wake up signal received from BCM via CAN communication.
Normal mode (wake-up)
- CAN communication is normally performed with other control units.
- Individual unit control by IPDM E/R is normally performed.
Low power consumption mode (sleep)
- Low power consumption control is active.
- CAN transmission is stopped.
Sleep Mode Activation
- IPDM E/R judges that the sleep-ready conditions are fulfilled when the electric motor switch is OFF and none of the conditions below are present. Then it transmits a sleep-ready signal (ready) to BCM via CAN communication.
- Outputting signals to actuators
- Output requests are being received from control units via CAN communication.
- IPDM E/R stops CAN communication and enters the low power consumption mode when it receives a sleep wake up signal (sleep) from BCM and the sleep-ready conditions are fulfilled.
Wake-Up Operation
- IPDM E/R changes from the low power consumption mode to the normal mode when it receives a sleep wake up signal (wake up) from BCM or any of the following conditions is fulfilled. In addition, it transmits a sleep-ready signal (not-ready) to BCM via CAN communication to report the CAN communication start.
- Electric motor switch ON
- Hood switch status changes.
- An output request is received from a control unit via CAN communication.
